Entergy Mississippi Launches $300 Million 'Superpower Mississippi' Grid Upgrade

The utility says new industrial revenue will cover the cost without raising household bills, subject to PSC approval.

Overview

  • The five-year program aims to cut power outages by about 50% across Entergy's 45-county service area serving roughly 459,000 customers.
  • Work begins immediately with plans for stronger poles, expanded vegetation management, and smart-grid devices with AI-enabled, self-healing capabilities.
  • Company leaders attribute funding to new industrial customers, including Amazon and AVAIO, and assert residential rates will not increase.
  • Two Public Service Commission members voiced support at the announcement, though the spending plan still requires commission approval.
  • Entergy cites a rise in tree-related outages in 2025, linked to drought-killed vegetation and recent storms, as a key driver for the upgrades.
